in the art as double-row-bearin s that is bearings having two series of rolling ele-' ments between concentric race members and which are designed to transmit radial as well as end thrust loads, in the direction of the axis of the bearings.

The invention contemplates two concentrically mounted racemembers, an inner and outer member with the two series of roller elements disposed therebetween and is further characterized by the construct on of one of the members, in two parts and with each part carrying one of the series of roller ele; ments. One of the objects of the invention'is to provide in such a type of anti-friction hearing, an arrangement whereby the parts are made of a relatively small number, are designed to be held accurately, rigidly and securely in theirproper relation when in active operation and in which theparts can be readily assembled or demounted when desired.

Broadly this object is attained by torxn ing one of the two race members" in two parts which parts are mounted for relative movement about an axis at right anglesto the axis of: the bearings with the movable element guided for movement eccentrieally relative to the opposed race member to permit the detachment of the movable element from the remaining parts oi the hearing;

The invention in its detail construction Various other objects and advantages ot the invention wlll be in part obvious from an inspection of the accompanying drawforth and claimed;

improvement 7 1n anti-frictlon bearlngs ot the type known struction ings and in part will be more fully set forth tain new and novel features of construction and combination of parts hereinafter set In the accompanying drawings: s Figure 1 1s alongitudinal view taken am:

showing the partial removal of the demount- The disclosures in all of the modifications "are" similar in that thereis shown an. outer race memberand an inner race member with "two series oi. roller elements'disposed there- 0t 161 and a two-part inner race member with ea h 'ofthe parts 2 and 3 provided respec' tively with oppositely disposed ball'tracks 21 and 31 facing the tracks 11 and 12 with e roller elements in the form or balls 6 disposed therebetween. The race member 3 is provided with an annular flange 32 which extends axially from the body portion 33 of the part 3 and projects towards andinto the correspondingpart 2, to'constitute the male element of a universally flexible joint. The

contour of the outer sideoi the fian e is a portion 1 of a sphere struck with a radius 0-5 from a pomt 41-. on theams of rotation otthe bearing asthe center. The balltracks There is also illustrated a; conventional" means 5 for maintaining the. rotating .elements in spaced relation. on the tracks as is usual in such, constructions.

The disclosure in Figure 8; is inserted simply to show. the adaptability of. the in vention to be utilizedxin connection 'with roller bearing structures havlng variable ratios between the angles of tl' rusts. It Wlll be'understood that the showing in Figureilu provides for approximately- 125 longitudinal thrust, while the disclosure in=-Figure 3 is designed to provide for approximately 90 of longitudinal thrust,

The modification illustrated in Figure 6 is disclosed to show the adaptability of. the invention to an arrangement in, which the outer race member rather than the inner race member. is formed of the two separable parts. In this disclosure the inner race member 34 is formed in one cylindrical piece of a general spool-shape. and is provided with. anannular recess 35 on the side thereof opposite portions of which recess provide roller tracks 36 and 37 facing-each other. The outer race member is formed inthis case of two parts coactingto form an in,

ternal universal joint'and including a fee male-member-l2 provided on oneside thereof with 'a spherical socket 153. The other part 23 .constitutesthe coactingma-le member and is provided with an inter-engaging surface.

24 struck from the center 4; on the axis of thebearmg as was described for the inner split member disclosure in Figure 1.

In both. forms of the disclosurean effort has been made to feature thesimplicity of construction and the minimizingof the nunr ber; of parts and for this reason the two-part the flange as athird part suitably fastened to the body-portion rather than in the form of the single casting illustrated.

either one of the parts of the two-part race member can be removed from its coacting part and carry with it the roller elements simply by rotating the movable parts relative to. each other and about an axis which In operationit will beunderstood that passes through the point 4 and. perpendicular to the axis of the bearing. In the showinp; in Figure 2 it will be noted that the part 2 is simply rotated about the part 3 with a sliding bearing and the inter-engaging spherical surfaces and tilted into such, apositionv aswill permit the upper side of the part 2 to'be withdrawn outwardly and upwardly from the traclrll. Thedemounted parts can then be lifted bodily out away from the other remaining parts. a

In the disclosure shown; in, Figure 7 the outer part 23is similarly rotated-or canted out of itsposition shown in Figure 6 again rotating the-parts about the center defined by the point 4.

It will be understood that by means of a device of the character such as herein disclosed, it is possible, when the two part race member is held in normal position to retain all of the advantages of roller bearings of the typeiouthned and at the same timeto provide such a construction as will readily permit the deinounting or the ready assembling of the parts constituting the bearings.
